| Fixed In Version: | dracut-004-322.el6 | Doc Type: | Bug Fix |
| Doc Text: |
Cause:
dracut makes use of "grep" without unsetting the environment variable GREP_OPTIONS.
Consequence:
If the user has set GREP_OPTIONS while calling yum or running dracut, usages of the "grep" tool could fail because of arbitrary options.
Fix:
dracut now unsets the GREP_OPTIONS environment variable.
Result:
User settings of the GREP_OPTIONS environment variable does not affect the correct operation of dracut anymore.

First alpha build for testing: http://people.redhat.com/harald/downloads/dracut/dracut-004-316.el6/ Would be nice, if you could test it. I can confirm that problem is resolved with dracut-004-316.el6 Reproduced with dracut-004-303.el6: [root@localhost ~]# rpm -i --force kernel-2.6.32-424.el6.x86_64.rpm warning: kernel-2.6.32-424.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f21541eb: NOKEY The default plymouth plugin (text) doesn't exist E: Failed to install /lib64/libnss_dns-2.12.so mkinitrd failed warning: %posttrans(kernel-2.6.32-424.el6.x86_64) scriptlet failed, exit status 1 [root@localhost ~]# rpm -q dracut dracut-004-303.el6.noarch [root@localhost ~]# Verified with dracut-004-335.el6: [root@localhost ~]# rpm -i --force kernel-2.6.32-424.el6.x86_64.rpm warning: kernel-2.6.32-424.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f21541eb: NOKEY [root@localhost ~]# rpm -q dracut dracut-004-335.el6.noarch [root@localhost ~]# System booted correctly after reboot.

Description of problem: kernel installation fails if environment contains GREP_OPTIONS="--color=always" variable. # rpm -q dracut-network dracut-network-004-283.el6.noarch # export GREP_OPTIONS="--color=always" # rpm -ihv kernel-2.6.32-279.22.1.el6.x86_64.rpm kernel-firmware-2.6.32-279.22.1.el6.noarch.rpm Preparing... ########################################### [100%] 1:kernel-firmware ########################################### [ 50%] 2:kernel ########################################### [100%] The default plymouth plugin (text) doesn't exist E: Failed to install /lib64/libnss_dns-2.12.so mkinitrd failed warning: %posttrans(kernel-2.6.32-279.22.1.el6.x86_64) scriptlet failed, exit status 1 Version-Release number of selected component (if applicable): dracut-network-004-283.el6.noarch How reproducible: 100% Steps to Reproduce: 1. be sure that dracut-network is installed 2. set up GREP_OPTIONS variable: # export GREP_OPTIONS="--color=always" 3. try to install new kernel Actual results: dracut fails with following message in dracut.log Mon Feb 18 13:55:34 MSK 2013 Err: Failed to install /lib64/libnss_ESC[01;31mESC[KdnsESC[mESC[K-2.12.so Expected results: no errors Additional info: with dracut debug we have found that problem occurs during execution /usr/share/dracut/modules.d/95nfs/install dracut_install $(for i in $(ls {/usr,}$LIBDIR/libnss*.so 2>/dev/null); do echo $i;done | egrep "$nsslibs") Using "egrep -q" resolved the problem.
